A saga...
I've been buying tyres from Costco as they are the closest and much cheaper than others. But they refused to sell and fit two all-season tyres, like Michelin Cross Climate, to the Carlsson, saying that I had to have either two summer tyres to match the ones that are still OK, or four all-season. I planned to go to all season, they have been fine on my 9-5 for the last two years, and I'm getting too old to keep swapping wheels from summer to winter. But I wanted to swap the Carlsson in stages.
I decided to put two of the winter tyres on the Carlsson as a temporary measure (not to be driven on) while I took two loose wheels in to get two new tyres. Then things got out of hand.
Yesterday I got everything ready, but it's her car and the wheel lock wasn't in the usual place. SWMBO looked everywhere, she said, and it wasn't found. So we packed up and I went to order a new key. I had one last look, and the locking key was there. I don't know how she missed it...
So, today we started again. I decided to use the trolley jack. Took it out and a couple of joints looked a bit rusty, so I went to service the jack. All went well until I came to grease the main pivot. The grease gun was solid with old grease, so that was cleaned and got working. Then I put it on the grease nipple which wobbled and fell out. The nipple was clearly something cheap as there was hardly any thread on it. But in the way of having a stash of "things that might be useful one day", I found a proper nipple which fitted. It was in a box with a Mercedes logo on it. It was brand new and unused. So now I am, I hope, all ready to change the wheels.
And we sold the Mercedes in 1978
